Historic president's name on a manuscript (5)
I believe the answer is:
adams
'historic president's' is the definition.
'adams' can be an answer for 'president's' (I've seen this before). I am not certain of the 'historic' bit.
'name on a manuscript' is the wordplay.
'name' becomes 'ada' ().
'on' means one lot of letters go next to another.
'a manuscript' becomes 'ms' (abbreviation for manuscript).
'ada'+'ms'='ADAMS'
Can you help me to learn more?
(Other definitions for adams that I've seen before include "Former US president" , "Douglas - (The Hitchhiker's Guide to the Galaxy)" , "revolutionary leader" , "Sort of apple" , "Name of two early US presidents" .)
